The new commit by Jesse that extended the fb_info with a skip_vt_switch element is the simplest example of a data structure expansion. We'd backport this by adding a static inline to compat so that new kernels muck with the new element and for older kernels this would be a no-op. This reduces the size of the backport and unclutters the required patch with #idefs, and insteads leaves only a replacement of the usage of the new elements with a static inline, this however would still be required on our end:
info->skip_vt_switch = true;
fb_enable_skip_vt_switch(info);So we'd then have to just add this static inline change for each new driver... There may be a way to get SmPL to do this for us...
Yeah I'm not attached to the direct structure reference; a couple of inlines are just as easy to read. So no argument from me.
Thanks,
